Flight safety is highly recognized as a critical successful factor for the management and operations of an airline company. Along side pilot’s capability and weather conditions, the quality of flight maintenance is the major factor that contributes to the safety of aviation. Since flight maintenance is mainly executed by maintenance workers, there is a constant need to understand the status of job satisfaction of the maintenance workers to ensure flight safety. This research looks at the issues of job satisfaction from the perspective of benefits programs, job involvement and organization commitment. By using Ridit analysis, this research identified that maintenance workers at different levels of positions achieved different degrees of satisfaction in the benefits programs offered by the company. By using principal component analysis, factors that contribute to the degree of job involvement and organization commitment had also been identified. We had also located the benefits variables that are mostly associated with work involvement and organization commitment. Through the empirical data of the research, we had shown that Marslow’s theory of progressive fulfillment of hierarchical needs may be modified to better describe human needs. Based on the results of this research, it is suggested from managerial perspective that (1)Work enthusiasm, responsibility and ability are the three characteristics that should receive due concerns in personnel recruitment and job training. (2)To encourage job involvement, company should implement better plans for career development, work safety, leisure activities and mess quality. (3)More recreation facilities should be provided for the relief of pressures from daily work.
